Six years, steel bars, and no tailstock—this is not your average DIY mini lathe project.
What started as a curiosity about what it takes to build a lathe turned into a long, ambitious journey to create one from scratch—without precision machinery, and with very little prior experience in mechanical engineering.
In this episode, I show how the project has progressed—cutting precision lead screws by hand, improvising stabilizers, and slowly turning raw steel into functioning parts.
Yes, the lathe is still alive. And it’s slowly building itself.
If you're new here, this isn’t just a homemade machine—it's a hands-on challenge to understand and build the machine that makes machines.
And if you've been waiting... well, it's finally time for an update.

![How to spot a fault in a circuit, like a pro : hands on electronics [1]](https://i.ytimg.com/vi/ye9dguKy_Cs/mqdefault.jpg "How to spot a fault in a circuit, like a pro : hands on electronics [1]
In this video I show the method to find out a fault on an electronic circuit board. In the specific case we have an ESC (Electronic Speed Control) that is used to control a washing machine motor (used to drive the spindle of a lathe) and somewhere in the circuit there is a faulty contact. It turns out it was a bad soldering that caused an uncertain contact, making the motor to start and stop randomly. The video shows the procedure to spot the exact point where the fault is present.
Wonder how to #faultfinding without schematic? Watch this video too: https://youtu.be/yjxuMwLN7zI

![The mindblowing #photoacoustic effect: #light makes materials to play #sound! - [Redone video]](https://i.ytimg.com/vi/zIQXlf1qLsM/mqdefault.jpg "The mindblowing #photoacoustic effect: #light makes materials to play #sound! - [Redone video]
A piece of fleece generates sound just projecting a modulated light! No electronics involved! (Aside the light modulator.)
*This plays sound JUST with light!*
I reproduced an experiment that led to the definition of the photoacoustic effect. This effect has been first discovered by Alexander Graham Bell, the inventor of the telephone and of the photophone. While this effect is widely exploited in photoacoustic spectroscopy, it is often overlooked by many.
So with this video I bring it to light ...so to say :-)
After a first failure in reproducing the experiment, after some research I managed to achieve results.
Encouraged, I developed a special #LED driver. The final result is amazing: a simple piece of fleece emits #music just for the radiated modulated light!
The effect is regarded to be caused by light induced thermal expansion and contraction of materials.
In doing this experiment I also stumbled upon a weird response from a piezoelectric sensor, with an unexpected and interesting effect that I showcased in a bonus extra section of the video.
